Sperling's Partial Report Procedure
In 1960, George Sperling became the first to use a partial report paradigm to investigate the bipartite model of VSTM. In Sperling's initial experiments in 1960, observers were presented with a tachistoscopic visual stimulus for a brief period of time (50 ms) consisting of either a 3x3 or 3x4 array of alphanumeric characters such as:
- P Y F G
- V J S A
- D H B U
Recall was based on a cue which followed the offset of the stimulus and directed the subject to recall a specific line of letters from the initial display. Memory performance was compared under two conditions: whole report and partial report.

Famous quotes containing the words partial and/or report:
“It is characteristic of the epistemological tradition to present us with partial scenarios and then to demand whole or categorical answers as it were.”
—Avrum Stroll (b. 1921)
“Men are born to write. The gardener saves every slip, and seed, and peach-stone: his vocation is to be a planter of plants. Not less does the writer attend his affair. Whatever he beholds or experiences, comes to him as a model, and sits for its picture. He counts it all nonsense that they say, that some things are undescribable. He believes that all that can be thought can be written, first or last; and he would report the Holy Ghost, or attempt it.”
—Ralph Waldo Emerson (1803–1882)
